HIRAM M. SMITH, OF RICHMOND, VIRGINIA.

METHOD OF OILING HORIZONTAL SHAFTS AND .AXIA-ES.

Specication of Letters Patent No. 1,552, dated April 15, 1840.

To all whom t may concern.'

Be it known that I, I-I. M. SMITH, of the city of Richmond, county of Henrico, and State of Virginia, have invented a new and Improved Mode of Oiling the Journals of all Horizontal Shafts and Axles; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a section through the middle of the box lengthwise. Fig. 2 is a transverse section also through the middle of the box.

The same letters refer to the same parts in Figs. l and 2.

A, cistern or oil cup, it consists of a cavity cast in the under half of a box or pillowblock of sufiicient depth to receive the wheel B, gate C, and spring D, allowing half an inch space under the center of the spring while the ends rest on the bottom, the length and width of the oil cup to be governed by the quantity of oil it is required to hold. The spring D, is a plain flat piece of springsteel curved as shown with its ends resting on the bottom of the oil cup without other fastening, it should be of suficient strength to support from 10 to 20 lbs. in the center. C, gate or sliding frame, it is cast of brass or other metal and slides into the oil cup between the guides E E E E and rests upon the spring D. B, oiler or feeder, it is made of cast-iron and turned perfectly round and smooth and rests in the gate C, in boxes open on top as shown.

F, is a wiper to keep the oil back when the supply would be too great without it, itconsists of a small wrought iron frame with knobs projecting from each side between the guides E E and resting on the upper end of the gate C, the other end is faced with thick leather on the under side and rests on the wheel. The under brass G, is made in any of the known forms excepting that it has flanges projecting to cover the opening into the oil cup in which gutters are provided to receive and carry the surplus oil back into the oil cup, and is a quarter of an inch shorter at each end than the pillow block to allow a cast ange to project from the pillow block by the ends of the brass to pre- Vwill admit, it will render the operation of the box more perfect to turn a neck to the journal andhave the lange from the pillow block project by "the'brass and lit around the neck as shown at H, in Fig. 2. ,i

I shows the depth ofl oil in the cup; J, surplus oil running back into the oil cup.

Fig. 3 represents the frontVV of abox with flanges to bolt it to the side of a timber, and is suitable for a threshing machine cylinder and other similar machines; A, is the orifice at which the oil is poured in; B a gage cock to show when the oil is up tothe wheel; C, cock to drawoii' thel oil when it has become muddy and unfit for use.

The operation is self evident.

to it by the spring will also revolve, and as it wades in oil at the bottom it will always be wet with it and impart a portionr of it Yto the journal vas the wheel rolls against it; as the journal receives oil above its wants it llo-ws over the edge of the brass into the gutterand runs back into the oil cup to be used again and again until unfit for use.

I intend to apply this box to all horizontal journals orbearings, and. particularly to R. R. car axles, altering the shape of the box from what I have just described to suit that purpose.

Vhat I claim as my invent-ion and desire to secure by Letters Patent is,

l. The wheel B working in an oil cup and in a sliding frame or gate acted upon by a spring which adapts it to any irregularity of height the bearing is subject to, as herein described. I disclaim it as a friction roller, as I do not intend it to support the bearing but merely to act as an oiler or feeder. i

2. I also claim the wiper and the gutters on each side of the bearing in combination with the wheel, as herein described.

H. M. SMITH.
